Objective: To discuss the application of portal vein embolization in two-stage precise hepatectomy. Methods: Clinical data of 7 patients who underwent two-stage precise hepatectomy after percutaneous transhepatic portal vein embolization guided by ultrasound and digital subtraction angiography were analyzed in this study. There were 3 cases in liver cirrhosis group and 4 cases in without liver cirrhosis group. Liver function and liver volume were detected in each group before and after portal vein embolization, and the effect of two-stage surgical resection was examined. Results: Percutaneous transhepatic portal vein embolization was successfully performed in all 7 patients. Future liver remnant increased and hepatic hypertrophy was found in 6 patients who completed two-stage precise hepatectomy afterward. Non-embolized liver hypertrophy was not enough to the conditions for two-stage hepatectomy after 8 weeks in the other patient of colorectal cancer with liver metastases. The patient underwent the therapy of associating liver partition and portal vein ligation for staged hepatectomy in other hospital. In both groups liver function was abnormal at the first day after the percutaneous transhepatic portal vein embolization (P<0.05) and recovered to normal 3-7 days later. No severe complication was found in this study. Conclusions: Portal vein embolization is safe and feasible, and increases the volume of future liver remnant significantly. It can provide the opportunity of two-stage precise hepatectomy.
